Documentary look at health care in the United States as provided by profit-oriented health maintenance organizations (HMOs) compared to free, universal care in Canada, the U.K., and France. Moore contrasts U.S. media reports on Canadian care with the experiences of Canadians in hospitals and clinics there. He interviews patients and doctors in the U.K. about cost, quality, and salaries. He examines why Nixon promoted HMOs in 1971, and why the Clintons' reform effort failed in the 1990s. He talks to U.S. ex-pats in Paris about French services, and he takes three 9/11 clean-up volunteers, who developed respiratory problems, to Cuba for care. He asks of Americans, "Who are we?"
